Mount Olympus

The abode of the gods. A massif of limestone and dolomite rising to 2917 meters between Thessaly and Macedonia, less than twenty kilometers from the Aegean Sea, dominating the Greek plains with a presence that has shaped three thousand years of myth, literature, and civilization. Mount Olympus — Όλυμπος to the Greeks — is the highest mountain in Greece, the country's first National Park since 1938, and a UNESCO Biosphere Reserve. Reaching the summit of Mytikas (from the Greek for "nose") means following the very path that ancient Greeks believed forbidden to mortals: from forests of pine and beech to alpine meadows, and finally a rocky ridge suspended between sky and sea where the last stretch demands hands on rock.

Quick Facts

The Ascent to Mytikas

The classic route to the summit of Mount Olympus starts from Prionia (1100 m), the highest point reachable by car, accessed from Litochoro via a paved road that climbs the Enipeas Gorge. The ascent is recommended as a two-day trek, with an overnight stay at Refuge Spilios Agapitos (2100 m), to manage effort wisely and start for the summit at dawn.

Day 1: From Prionia to Refuge Spilios Agapitos

From Prionia you take the E4 trail, a well-marked path climbing through a dense forest of black pines, beeches, and firs. The route gains elevation steadily but is never exposed, with a mix of earthen and rocky ground. You gain approximately 1000 meters of elevation over 6.6 km, with a walking time of 2.5–3 hours. Refuge Spilios Agapitos — also known as Refuge A — is a welcoming, well-managed facility offering dormitory beds, hot meals, and drinking water. Booking ahead is recommended during high season — for information, availability and contacts, visit the official refuge website.

Day 2: From the Refuge to the Summit and Back

Departure at dawn from the refuge, following red trail markers that climb above the treeline into the alpine zone. The trail crosses the Zonaria, a long traverse across stony terrain with panoramas stretching over the Thessalian plain and the Aegean Sea. After approximately 3 km and 750 meters of elevation gain (1.5–2 hours) you reach the saddle of Skala (2866 m), the last summit reachable at standard hiking difficulty.

From Skala to Mytikas — The Kakoskala Ridge

From Skala begins the most challenging and spectacular section. The Kakoskala ridge ("the bad staircase") connects Skala to Mytikas across roughly 400 meters of distance and 51 meters of elevation gain on exposed limestone rock. The passages require the use of hands and reach Grade II: it is not technical mountaineering, but sure-footedness, a head for heights, and constant attention are essential. The rock is friable in places and the presence of other hikers can trigger rockfall — a helmet is strongly recommended. The section takes 30–60 minutes to ascend and about the same to descend.

As an alternative, those who prefer not to tackle the Kakoskala can reach Skolio (2911 m), Olympus's second-highest peak, accessible from Skala via a hiking trail with no scrambling required.

Descent

The descent follows the same route: Mytikas → Skala → Refuge A → Prionia. From the refuge to Prionia takes about 2 hours, from the summit to the refuge approximately 2.5–3 hours. It is possible to complete the entire round trip in a single day, but only very fit and fast hikers should consider this option.

Oxygenation and Acclimatization

At 2917 meters barometric pressure grants 70% of the oxygen available at sea level. Olympus places the hiker in a moderate altitude zone, where hypoxia manifests primarily during intense exertion but rarely reaches critical levels for healthy, fit individuals.

Typical summit SpO₂ for a healthy individual ranges between 85 and 90% — values that cause mild breathlessness under exertion but do not pose an acute risk for most people. The distinctive challenge of Olympus is that the final section — the Kakoskala ridge — demands athletic movements and concentration on exposed rock precisely when the body begins to feel the thinning air. The anaerobic effort of scrambling passages amplifies the perception of breathlessness and can cause mild dizziness if breathing is not managed carefully.

Adopt diaphragmatic breathing on the most demanding sections: inhale through the nose for four seconds, exhale through the mouth for six. Stop to catch your breath before each exposed passage on the Kakoskala rather than tackling it while winded. If you experience intense headache, nausea, or dizziness that does not resolve with rest, descend immediately. The overnight stay at Refuge A (2100 m) already provides excellent pre-acclimatization.

Note: This advice is informational and does not replace medical consultation. Consult a physician before undertaking demanding ascents, especially if you have pre-existing cardiac or respiratory conditions.

Physical Preparation

Olympus requires no advanced mountaineering skills up to Skala, but the Kakoskala ridge demands confidence with exposed rock scrambling and sure-footedness on loose terrain. The overall elevation gain from Prionia is significant and requires good endurance.

Those without scrambling experience on exposed rock should limit themselves to the Skolio summit (2911 m) or hire a local guide for the Kakoskala section.

Equipment

Olympus combines a long hiking approach with a final scrambling section on rock. Equipment must address both demands.

Essential:

• Sturdy, high-ankle hiking boots with rigid soles — the limestone on the Kakoskala requires grip and ankle support
• Layered clothing and windproof/waterproof jacket — Olympus weather changes with extreme speed, even in midsummer
• At least 2 liters of water — there are no water sources between Refuge A and the summit
• SPF 50+ sunscreen and sunglasses — exposure is intense on the summit ridge
• Sufficient food for summit day (the refuge is the last supply point)

Recommended:

• Climbing helmet — the risk of rockfall on the Kakoskala is real, especially when other parties are present
• Trekking poles — useful on the long ascent to the refuge and during descent, to be stowed in the backpack on the Kakoskala
• Light via ferrata gloves — to protect hands on rough rock
• Pocket pulse oximeter to monitor SpO₂ during the ascent
• Headlamp (for the dawn departure from the refuge)

Historical Notes and Curiosities

Mount Olympus is not merely a mountain: it is the cradle of Western civilization, the place where the Greeks located the dwelling of the gods and the throne of Zeus. For three thousand years no mortal dared climb the summit, and the clouds that perpetually shroud Mytikas fed the myth of a peak unreachable, hidden from human eyes.

Homer in the Odyssey describes Olympus as a place where "neither is it shaken by winds, nor ever wet with rain, nor does snow fall upon it; but cloudless air spreads about it" — an immutable paradise where the gods feasted on nectar and ambrosia. Zeus ruled from his throne on the highest peak, surrounded by Hera, Athena, Apollo, Aphrodite, Ares, Hephaestus, Artemis, Hermes, Dionysus, Demeter, and Poseidon — the twelve Olympian gods who shaped the imagination of the entire Western world.

The first ascent: Mytikas was conquered on August 2, 1913 by Christos Kakkalos, a local hunter and guide from Litochoro, together with the Swiss Frédéric Boissonnas (photographer) and Daniel Baud-Bovy (writer). Kakkalos, who knew every crevice of the mountain, was the first to reach the summit, inaugurating the era of modern mountaineering in Greece. The feat was long contested by those who considered it sacrilege to tread upon the gods' abode.

Key milestones:

• 1913 — First documented ascent of Mytikas by Kakkalos, Boissonnas, and Baud-Bovy
• 1938 — Establishment of Greece's first National Park on Mount Olympus, protecting 44,500 hectares
• 1981 — UNESCO declares the massif a Biosphere Reserve for its extraordinary biodiversity
• 2019 — Designation as a site of particular European natural importance (Natura 2000)

Curiosities:

• The name Mytikas means "nose" in Greek, after the pointed shape of the peak as seen from below
• The peak Stefani (2909 m) is also called the Throne of Zeus for its shape resembling a majestic seat
• The massif hosts over 1700 plant species, of which 23 are endemic and found nowhere else on Earth
• The Enipeas Gorge, climbed on the way to Prionia, takes its name from the river god who loved Tyro in Greek mythology
• Olympus lies just 18 km as the crow flies from the Aegean Sea: the contrast between the beaches of the Olympic Riviera and the snow-capped summit is one of Greece's most spectacular views
• The sanctuary of Dion, at the foot of Olympus, was the sacred site where the Macedonians — including Alexander the Great — offered sacrifices to Zeus before military campaigns
